[wix-users] [EXTERNAL] - Executing a batch script using custom action before File Copy/Install Files - Help Needed

[Lewis Henderson]

Hi Kathir,

I had a similar requirement - I needed to use batch scripts to interact with an already-installed utility to perform validation prior to InstallExecure.  I added the batch files as Binary table entries, then passed those Id's to a couple of custom actions (mine were C instead of C#), one was immediate execution and the other was deferred.  I can't post my CA code, but you should be able to find the information you need using a google search for "batch files in wix".  The essence is to extract the binary from the installer using MsiOpenDatabase|MsiGetActiveDatabase, MsiDatabaseOpenView (using the Binary ID in the query), MsiViewExecute, and MsiViewFetch, then create a local copy of the batch file on disk using MsiRecordReadStream to populate it, then you can execute the batch script via CreateProcess, or even something as simple as system().  Then of course you'd do your cleanup.  For the Immediate CA, I passed the Binary ID and parameters using fixed WiX properties (set in a Dialog) and for the deferred CA I used a semicolon delimited string in the CA Data.  For my case, I created the two CA's that only parsed the parameters using the proper methodology, then they both called a common subroutine to perform the binary extraction and execution.

I hope this helps.

Subject: [EXTERNAL] - [wix-users] Executing a batch script using custom action before File Copy/Install Files - Help Needed

Hello All,

 

   I am new to WiX Toolset.

   

   I have a requirement to execute a batch script( there are scripts used for some custom pre-requisite check) before the File Copy/ Install Files,

   Is there a mean to add the batch script as binary and execute using a  C# Custom Action? 

 

   Please let me know is there a solution to address this requirement.

   Kindly help me in this regard.

 

Thanks,

Kathir
